Survival was monitored every 6 - 12 h after injection. The data shown represent a combination of two independent experiments. Statistical comparison of survival was performed with a log-rank test. **, P < 0.01, *, P < 0.05. (B) Serum samples were obtained from these mice and subjected to ELISA to examine MCP-5 levels. (C-D) The serum levels of LDH and albumin were assessed. (E) Lung tissues were removed, and the percentages of macrophages were analyzed by flow cytometry. (B-E) The data are representative of one of two independent experiments. Significance was calculated using a two-way ANOVA. **, P < 0.01, * P < 0.05, n.s., not significant. (F) Rosa26LSL-MLS-Stat3 and Rosa26LSL-MLS-Stat3;LyzCre/+ mice were injected with 10 mg/kg curcumin prior to LPS (20 mg/kg). Survival was monitored every 6 - 12 h after injection. Statistical comparison of survival was performed with a log-rank test. **, P < 0.01, *, P < 0.05. (G) BMDMs of the indicated genotypes were treated with 8 μM curcumin for 20 h and incubated with either 100 ng/mL LPS (30 min) or 100 ng/mL IFN-α (1 h) before harvesting. The cells were harvested, lysed, and subjected to a Western blot analysis. The membranes were blotted with the indicated antibodies. (H) Cells were treated with 8 μM curcumin for 20 h and incubated with 100 ng/mL LPS for another 15 min. Nuclei and cytoplasmic fractions were extracted. The levels of the indicated proteins were analyzed by a Western blot analysis. (I) BMDMs were treated with curcumin. After 20 h, these cells were stimulated with or without 100 ng/mL LPS for 6 h before loading. BMDMs were then treated sequentially with BSA-conjugated palmitate, oligomycin, FCCP, and ETO as indicated. The data are representative of one of two independent experiments performed with n = 5. (J) 4-OHT-treated BMDMs were treated with curcumin for 20 h, and then, the BMDMs were exposed to 100 ng/mL LPS and 10 μmol/L MG132 for an additional 6 h before harvesting. The cell lysates were isolated, IP with an anti-CPT1a antibody and analyzed by a Western blot analysis using an anti-ubiquitin antibody. (G, H and J) The results shown are representative of one of three independent experiments. (K) Schematic representation of the mitochondrial STAT3-mediated increase in FAO in a USP50-dependent manner in the LPS-induced sepsis model. Upon the LPS stimulation, mitochondrial STAT3 could induce CPT1a stabilization by promoting USP50 expression and facilitating CPT1a-USP50 binding, leading to a switch from glucose to an increased reliance on FAO for ATP production, which, in turn, further enhanced NF-κB nuclear localization, leading to a great amount of cytokine production.$

Q04206_TF65_HUMAN

機能:

NF-kappa-B is a pleiotropic transcription factor present in almost all cell types and is the endpoint of a series of signal transduction events that are initiated by a vast array of stimuli related to many biological processes such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The heterodimeric RELA-NFKB1 complex appears to be most abundant one. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. The NF-kappa-B heterodimeric RELA-NFKB1 and RELA-REL complexes, for instance, function as transcriptional activators. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. The inhibitory effect of I-kappa-B on NF-kappa-B through retention in the cytoplasm is exerted primarily through the interaction with RELA. RELA shows a weak DNA-binding site which could contribute directly to DNA binding in the NF-kappa-B complex. Beside its activity as a direct transcriptional activator, it is also able to modulate promoters accessibility to transcription factors and thereby indirectly regulate gene expression. Associates with chromatin at the NF-kappa-B promoter region via association with DDX1. Essential for cytokine gene expression in T-cells. The NF-kappa-B homodimeric RELA-RELA complex appears to be involved in invasin-mediated activation of IL-8 expression.

PTMs:

Ubiquitinated by RNF182, leading to its proteasomal degradation. Degradation is required for termination of NF-kappa-B response.

Monomethylated at Lys-310 by SETD6. Monomethylation at Lys-310 is recognized by the ANK repeats of EHMT1 and promotes the formation of repressed chromatin at target genes, leading to down-regulation of NF-kappa-B transcription factor activity. Phosphorylation at Ser-311 disrupts the interaction with EHMT1 without preventing monomethylation at Lys-310 and relieves the repression of target genes (By similarity).

Phosphorylation at Ser-311 disrupts the interaction with EHMT1 and promotes transcription factor activity (By similarity). Phosphorylation on Ser-536 stimulates acetylation on Lys-310 and interaction with CBP; the phosphorylated and acetylated forms show enhanced transcriptional activity. Phosphorylation at Ser-276 by RPS6KA4 and RPS6KA5 promotes its transactivation and transcriptional activities.

Reversibly acetylated; the acetylation seems to be mediated by CBP, the deacetylation by HDAC3 and SIRT2. Acetylation at Lys-122 enhances DNA binding and impairs association with NFKBIA. Acetylation at Lys-310 is required for full transcriptional activity in the absence of effects on DNA binding and NFKBIA association. Acetylation at Lys-310 promotes interaction with BRD4. Acetylation can also lower DNA-binding and results in nuclear export. Interaction with BRMS1 promotes deacetylation of Lys-310. Lys-310 is deacetylated by SIRT2.

S-nitrosylation of Cys-38 inactivates the enzyme activity.

Sulfhydration at Cys-38 mediates the anti-apoptotic activity by promoting the interaction with RPS3 and activating the transcription factor activity.

Sumoylation by PIAS3 negatively regulates DNA-bound activated NF-kappa-B.

Proteolytically cleaved within a conserved N-terminus region required for base-specific contact with DNA in a CPEN1-mediated manner, and hence inhibits NF-kappa-B transcriptional activity.

タンパク質ファミリー:

The transcriptional activation domain 3/TA3 does not participate to the direct transcriptional activity of RELA but is involved in the control by RELA of the accessibility of target gene promoters. Mediates interaction with ZBTB7A.

The transcriptional activation domain 1/TA1 and the transcriptional activation domain 2/TA2 have direct transcriptional activation properties (By similarity). The 9aaTAD motif found within the transcriptional activation domain 2 is a conserved motif present in a large number of transcription factors that is required for their transcriptional transactivation activity (PubMed:17467953).

Figure 8 Curcumin relieved LPS-induced sepsis. (A) After the last 4-OHT injection, Rosa26LSL-MLS-Stat3 and Rosa26LSL-MLS-Stat3;UbcERT2Cre/+ mice were injected with curcumin prior to LPS. Survival was monitored every 6 - 12 h after injection. The data shown represent a combination of two independent experiments. Statistical comparison of survival was performed with a log-rank test. **, P < 0.01, *, P < 0.05. (B) Serum samples were obtained from these mice and subjected to ELISA to examine MCP-5 levels. (C-D) The serum levels of LDH and albumin were assessed. (E) Lung tissues were removed, and the percentages of macrophages were analyzed by flow cytometry. (B-E) The data are representative of one of two independent experiments. Significance was calculated using a two-way ANOVA. **, P < 0.01, * P < 0.05, n.s., not significant. (F) Rosa26LSL-MLS-Stat3 and Rosa26LSL-MLS-Stat3;LyzCre/+ mice were injected with 10 mg/kg curcumin prior to LPS (20 mg/kg). Survival was monitored every 6 - 12 h after injection. Statistical comparison of survival was performed with a log-rank test. **, P < 0.01, *, P < 0.05. (G) BMDMs of the indicated genotypes were treated with 8 μM curcumin for 20 h and incubated with either 100 ng/mL LPS (30 min) or 100 ng/mL IFN-α (1 h) before harvesting. The cells were harvested, lysed, and subjected to a Western blot analysis. The membranes were blotted with the indicated antibodies.

(K) Schematic representation of the mitochondrial STAT3-mediated increase in FAO in a USP50-dependent manner in the LPS-induced sepsis model. Upon the LPS stimulation, mitochondrial STAT3 could induce CPT1a stabilization by promoting USP50 expression and facilitating CPT1a-USP50 binding, leading to a switch from glucose to an increased reliance on FAO for ATP production, which, in turn, further enhanced NF-κB nuclear localization, leading to a great amount of cytokine production.
